Burstiness

Burstiness or text burstiness refers to the pattern of sentence length in written text. Humans tend to write in a bursty fashion with short and long sentences interspersed, while machines tend to write uniformly with mostly sentences of the same length. GPTZero primarily detects this difference. To measure text burstiness, one looks at the probability distribution of sentence length. A neat, uniform probability distribution indicates a computer-generated text, while a messy, inconsistent distribution suggests human writing.
